Yes it is conductive.
It's usually thin enough for even modest voltages to punch through but, yes, its orders of magnitude worse than silver.An IEEE paper [1] states: ".. Silver sulfide is not a conductive material, and having a contact surface covered with a corrosion layer may decrease electrical conductivity significantly. The effect of corrosion on electrical properties of the contact depends mainly on the thickness of the corrosion layer .." -> Hence silver connectors are not common, but silver cable is.

In any case it offers zero as to audible change/improvement over plain copper.It's usually thin enough for even modest voltages to punch through but, yes, its orders of magnitude worse than silver.
Objective achieved!In any case it offers zero as to audible change/improvement over plain copper.
It only lightens your wallet.
I thought it was a picture of Sal1950 himself.+1 for having a picture of David Gilmour
Doesn't take a lot to punch through the black tarnish.I have a pair of silver foil speaker cables with crimp on plugs. The resistivity is no different if they are freshly polished or covered in black sulphide. I've cleaned them twice, measured them both times. No different on a 5 digit meter. So any difference is sub miliohm for a 3m pair.
All of those.What cables do you use in your systems?
